FOSTER L B CO

Evaluation of Disclosure Controls and Procedures

L.B. Foster Company carried out an evaluation, under the supervision and with the participation of the Company’s management, including the Chief Executive Officer and the Chief Financial Officer, of the effectiveness of the design and operation of the Company’s disclosure controls and procedures (as defined in Rule 13a–15(e) under the Securities Exchange Act of 1934, as amended (“the Exchange Act”) as of the end of the period covered by this report. Based on that evaluation, the Chief Executive Officer and Chief Financial Officer concluded that, due to a material weakness in our internal control over financial reporting described below, our disclosure controls and procedures were not effective as of December 31, 2024.

Management's Report on Internal Control Over Financial Reporting

The management of L.B. Foster Company is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Exchange Act Rule 13a-15(f). L.B. Foster Company's internal control system is designed to provide reasonable assurance to the Company's management and Board of Directors regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with accounting principles generally accepted in the United States. All internal control systems, no matter how well designed, have inherent limitations. Accordingly, even effective controls can provide only reasonable assurance with respect to financial statement preparation and presentation.

Our management, including the Chief Executive Officer and Chief Financial Officer, assessed the effectiveness of our internal control over financial reporting as of December 31, 2024. In making this assessment, management used criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (“COSO”) in Internal Control - Integrated Framework (2013 Framework). Based on that evaluation, including the existence of the material weakness, discussed herein, the Chief Executive Officer and Chief Financial Officer concluded that our internal control over financial reporting was not effective as of December 31, 2024.

Material Weakness in Internal Control over Financial Reporting

A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of the Company’s annual or interim Consolidated Financial Statements will not be prevented or detected on a timely basis. We have identified the following material weakness in internal control over financial reporting as of December 31, 2024.

As discussed in our Amended 10-K and our Quarterly Reports on Form 10-Q/A for the quarters ended March 31, 2024 and June 30, 2024, the Company concluded it did not design effective controls related to the accounting for, and disclosure of, non-recurring complex transactions. This material weakness resulted in an immaterial error in the Company's previously issued Consolidated Statement of Operations included in the Original Form 10-K for the year ended December 31, 2023, and a material error in the Company’s previously issued Unaudited Condensed Consolidated Financial Statements, which errors were subsequently corrected in the above mentioned amendments for the fiscal period ending December 31, 2023 and the quarterly periods ending March 31, 2024 and June 30, 2024.

Management's Remediation Efforts

In response to the material weakness described above, with the oversight of the Audit Committee of our Board of Directors, the Company will conduct more thorough and diligent accounting research and, when necessary, engage third-parties to assist with the accounting for, and disclosure of, non-recurring complex transactions.

The remediation efforts are intended both to address the identified material weakness and to enhance our overall internal control environment. The Company is committed to continuous improvement of its internal control over financial reporting and will continue to diligently review and enhance its internal controls, as necessary. The Company cannot be assured that the measures we have taken to date, or that we may take in the future, will be sufficient to remediate the material weakness we identified or avoid future material weaknesses. Accordingly, there could continue to be a reasonable possibility that a material misstatement of our consolidated financial statements would not be prevented or detected on a timely basis.

Changes in Internal Control Over Financial Reporting

Other than the material weakness described above, there were no changes to our “internal control over financial reporting” (as such term is defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) that occurred during the year ended December 31, 2024, and that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

A material weakness is a deficiency, or combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of the company’s annual or interim financial statements will not be prevented or detected on a timely basis. The following material weakness has been identified and included in management’s assessment. Management has identified a material weakness related to the design of controls related to the accounting for, and disclosure of, non-recurring complex transactions.

Basis for Opinion

The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting included in the accompanying Managements’ Report on Internal Control Over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects.

Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

Definition and Limitations of Internal Control Over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.
